Surveillance decision

Surveillance decision

We will not update the guideline at this time.

Reason for the decision

We found 44 new studies through surveillance of this guideline.

This included new evidence on assessment, diagnosis, and management of primary headaches that supports current recommendations. We asked topic experts whether this new evidence would affect current recommendations on NICE guideline CG150. Generally, the topic experts thought that an update was not needed.

None of the new evidence considered in surveillance of this guideline was thought to have an effect on current recommendations.

Other clinical areas

We also found new evidence that was not thought to have an effect on current NICE guideline CG150. This evidence related to the use of occipital nerve block in people with chronic or episodic migraine (with or without aura) and the use of non-invasive nerve stimulators in people with chronic or episodic migraine (with or without aura) or cluster headache.

Equalities

One topic expert highlighted an equality issue in people with severe and profound intellectual disability: 'people with severe and profound intellectual disability or communication disorder cannot give a clear history of or complain of headache.' The NICE guidelines on learning disabilities note the challenges of identifying physical health in this population and make recommendations.

Overall decision

After considering all the new evidence and views of topic experts, we decided that no update is necessary for this guideline.
